OBJECTIVE:
To explore the relation between the behavior psychology analysis of partial mechanical injuries and the nature of death in high-falling cases, and provide reference, for such cases.
METHODS:
Of 311 death victims of high-falling injuries collected from 2008 to 2013, 205 cases were associated with partial mechanical injuries. The characteristics of injury formation, preliminary crime scene traces, fatal injury of high-falling, and text messages were all retrospectively analyzed.
RESULTS:
According to the investigation of preliminary crime scene traces, fatal injury of high-falling and text message, there were 86 suicide, 24 accident and 95 uncertainty in the 205 cases. According to the behavior psychology analysis of partial mechanical injuries, there were 80 suicide, 11 accident, and 4 homicide in the 95 uncertainty cases.
CONCLUSION
The partial mechanical injuries uncertainly caused by high-falling correlate with the manner of high-falling death. According to the behavior psychology analysis of the partial mechanical injuries in high-falling death cases, the presumption of high-falling death is usually accurate

OBJECTIVETo investigate the expression of connective tissue growth factor (CTGF) in osteoarthritis chondrocytes, and the relationship between CTGF, macrophage colony-stimulating factor (M-CSF) and cartilage degeneration.
METHODSTen New Zealand white rabbits were randomly divided into the normal group and OA model group established by Hulth's method. Sections were stained with Safranin O for histological examination. The cartilage histological characteristics were observed according to the method of Mankin. Immunohistochemical staining was performed. Articular cartilages were observed with microscopy and the image analysis method was used to measure the expression intensity of CTGF and M-CSF in each group, and the correlations of the expression of CTGF, M-CSF and cartilage degeneration were analyzed by statistics.
RESULTSImmunohistochemical staining indicated that the expression intensity of CTGF, M-CSF in untreated group was significantly increased as compared with that in the normal group (P<0.05). Statistical analysis showed that there was a correlation between the expression of CTGF, M-CSF and cartilage degeneration (r=0.634, r=0.542, P<0.01 respectively).
CONCLUSIONThe expression of CTGF and M-CSF protein is up regulated in osteoarthritis chondrocytes, which suggests that the activation of M-CSF is involved in the production of CTGF. CTGF and M-CSF play an important role in the pathogenesis of cartilage degeneration.

Toll-like receptors (TLRs) are germline-encoded pattern recognition receptors (PRRs) that play a central role in host cell recognition and responses to virus infection, leading to the production of interferons (IFNs) and proinflammatory cytokines. In parallel, in order to establish an infection, viruses have to develop exclusively strategies to interfere with TLRs signaling, particularly some important adaptors activation such as MyD88, NF-kappaB, TRIF and IRFs, and suppress or escape host's antiviral immune response. In this paper, we review the latest findings on the various strategies used by viruses to modulate TLRs-mediated innate immune response, with special emphasis on immune evasion mechanism of VACV, HCV and HIV. By highlighting recent progress in these areas, we hope to convey a greater understanding of how viruses hamper TLRs signaling and how to overcome viral infection.

OBJECTIVETo investigate the expressions of matrix metalloprotein-2 (MMP-2) and tissue inhibitor of metallopeptidase inhibitor-1 (TIMP-1) in the renal allografts of patients with chronic active antibody-mediated rejection (ABMR), and explore their role in the pathogenesis of ABMR.
METHODSImmunohistochemistry and computer-assisted image analysis were used to detect the expression of MMP-2 and TIMP-1 in the renal allografts of 46 patients with interstitial fibrosis and tubular atrophy (IF/TA), with 15 normal renal tissue specimens as the control. The association of MMP-2 and TIMP-1 with the pathological grade of IF/TA in ABMR was analyzed.
RESULTSThe expressions of MMP-2 and TIMP-1 significantly increased in the renal tissues of the patients as compared with the normal renal tissues (P<0.05). MMP-2 expression tended to decrease, while TIMP-1 and serum creatinine increased with the pathological grades of IF/TA (P<0.05). In IF/TA group, the expression of TIMP-1 was positively correlated to serum creatinine level (r=0.718, P=0.00<0.05).
CONCLUSIONAbnormal expressions of MMP-2 and TIMP-1 can promote the development of renal fibrosis in chronic ABMR.

This study was aimed to investigate the killing activity of cytokine-induced killer (CIK) cells after being incubated with autologous tumor cell lysate-pulsed dendritic cells (DC) and to evaluate the clinical efficacy and side effect of autologous tumor cell lysate-loaded DC in combination with CIK on relapsed or refractory non-Hodgkin's lymphoma (NHL). Peripheral blood mononuclear cells (PBMNC) were isolated from 9 patients with NHL, and cultured with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) to produce DC. The DC were pulsed with autologous tumor cell lysate. T lymphocytes from PBMNC were cultured with interferon-gamma (IFN-gamma), IL-2, CD3-moAb, and IL-1alpha to prepare CIK. After receiving the immunotherapy of DC and CIK, immunologic and clinical responses were evaluated. The results showed that the AgNOR, CD3(+)CD8(+) and CD3(+)CD56(+) ratio were markedly improved after the immunotherapy (p < 0.01); IFN-gamma and IL-12 levels in supernatant of DC-CIK group were higher than that in CIK group (p < 0.01); Tumor size were significantly decreased after the immunotherapy (p < 0.05). Except transient fever and chill, no remarkable adverse event happened during or after the treatment. It is concluded that the autologous tumor cell lysate-pulsed DC in combination with CIK show ability to specifically kill the lymphoma cells, obviously increases the IS value of Ag-NOR in peripheral lymphocytes, secretes cytokines higher than CIK cells alone. This combination displays the short-term satisfied efficacy on NHL through inducing specific antitumor immunity, and can be used as an effective adjuvant measure for the routine therapy of NHL.

OBJECTIVETo analyze the correlation between drug exposure (AUC0-4) and blood concentration of different sample points during Neoral absorption phase in Chinese adult liver transplant recipients, and to evaluate the possibility of using post-dose 2 hour level (C2) as a surrogate marker of AUC0-4 for the therapeutic drug monitoring (TDM) of Neoral.
METHODSNeoral levels at 0, 1, 2, 3, and 4 hours (C1, C2, C3, C4) after morning dose of 22 de novo Chinese adult liver transplant recipients were monitored during different posttransplant periods. Liner regression was used to analyze the correlation between CsA concentration at different time points and the AUC0-4.
RESULTSThe best correlation was found at C2, while the correlation of C0 was the lowest. During following-up, the correlation between C2 and AUC0-4 was very stable.
CONCLUSIONC2 had the best correlation with drug exposure. This correlation is very stable. C2 may be used as a good surrogate marker of AUC0-4 for the TDM of Neoral.

Objective To explore the role of regulatory T-lymphocytes(Treg) in the immune pathogenesis of suba-cute thyroiditis (SAT). Methods The proportion of Treg in CD4+T cells in peripheral blood of 46 SAT patients and15 controls was detected using flow cytometry. And the concentration of interleukin-10(IL-10), transforming growth factor-beta1(TGF-β1) and prostaglandin E2(PGE2) in serum of 46 SAT patients and 15 controls was measured with ELISA. In addition, the Forkhead box protein 3 (Foxp3) positive cells in thyroid tissue of 29 SAT patients and20 controls was detected by immunohistochemistry. Results The proportion of Treg in peripheral blood of SAT pa-tients was significantly lower than that of controls (P<0.05). And the concentration of TGF-β1 in serum of SAT patients was apparently higher than that of controls(P<0.05). Additionally, the positive rate of Foxp3 in thyroid tissue of SAT patients was markedly higher than that of controls(P<0.05).Conclusions The decrease of Treg may play an important role in the immune pathogenesis of SAT.

Buxue Yimu Pill (BYP) is a classic gynecological medicine in China, which is composed of Angelica sinensis (Oliv.) Diels, Leonurus japonicus Houtt, Astragalus membranaceus (Fisch.) Bunge, Colla corii asini and Citrus reticulata Blanco. It has been widely used in clinical therapy with the function of enriching Blood, nourishing Qi, and removing blood stasis. The current study was designed to determine the bioactive molecules and therapeutic mechanism of BYP against hemorrhagic anemia. Herein, GC-MS and UPLC/Q-TOF-MS/MS were employed to identify the chemical compounds from BYP. The genecards database (https: //www.genecards.org/) was used to obtain the potential target proteins related to hemorrhagic anemia. Autodock/Vina was adopted to evaluate the binding ability of protein receptors and chemical ligands. Gene ontology and KEGG pathway enrichment analysis were conducted using the ClusterProfiler. As a result, a total of 62 candidate molecules were identified and 152 targets related to hemorrhagic anemia were obtained. Furthermore, 34 active molecules and 140 targets were obtained through the virtual screening experiment. The data of molecular-target (M-T), target-pathway (T-P), and molecular-target-pathway (M-T-P) network suggested that 32 active molecules enhanced hematopoiesis and activated the immune system by regulating 57 important targets. Pharmacological experiments showed that BYP significantly increased the counts of RBC, HGB, and HCT, and significantly down-regulated the expression of EPO, IL-6, CSF3, NOS2, VEGFA, PDGFRB, and TGFB1. The results also showed that leonurine, leonuriside B, leosibiricin, ononin, rutin, astragaloside I, riligustilide and levistolide A, were the active molecules closely related to enriching Blood. In conclusion, based on molecular docking, network pharmacology and validation experiment results, the enriching blood effect of BYP on hemorrhagic anemia may be associated with hematopoiesis, anti-inflammation, and immunity enhancement.
